There are many kinds of inv器科erters, which can be classified accord劇筆ing to different methods.
1. According to到就 the frequency of invert在慢er output AC energy, it can be d件路ivided into power freque拿唱ncy inverter, intermediate frequency 議都inverter and high frequency invert黃請er. The frequency of power頻船 frequency inverter is 50-我資60Hz; the frequency of intermedia近文te frequency inverter is gene水鐘rally 400hz-10khz; the fr低房equency of high frequ雜媽ency inverter is generally 場北10khz-mhz.
2. According to the phase numbe玩我r of inverter output, it can b件生e divided into single-phase inve了弟rter, three-phase invert小看er and multi-phase inve件放rter.
3. According to the dire器土ction of the output ele樹們ctric energy of the inverter, it can b開音e divided into active inverter and 知他passive inverter. The inver好女ter that transmits the electric energ拿爸y output by the inver坐民ter to the industrial power grid is cal外街led the active inverter; the inverter農風 that transmits the e問靜lectric energy output by the為到 inverter to a certain electric loa森媽d is called the passive 關快inverter.
4. According to the form of in媽老verter main circuit, it can be 通拿divided into single ended inv好光erter, push-pull inverter, half b間關ridge inverter and full bridge i雨林nverter.
5. According to the的花 types of main switching devices of 什南inverter, it can be divided歌人 into thyristor inverter, transi視答stor inverter, field effect inve很上rter and insulated gate bi計看polar transistor (IGBT) inver技又ter, etc. It can also be divide不說d into two categories: hal南廠f control inverter and full contro那文l inverter. The former does not h都身ave the ability of self turning年很 off, and the compon呢秒ents lose the control下關 function when they are turned on, so道議 it is called "semi controlled&影草quot; ordinary thyristor;年廠 the latter, with the ability員腦 of self turning off, that is,湖錯 the on-off and on-off with明得out components can be controll舊跳ed by the control pole,船木 so it is called "fully c這玩ontrolled", power field effe外相ct transistor and insu如農lated gate double weight t湖章ransistor (IGBT), etc. 拿生It belongs to this category.
6. According 討小to DC power supply, it can be divid到章ed into voltage source inverter (V費靜SI) and current source inverter (CSI). 劇門For the former, the DC voltage 內化is nearly constant and the output volta劇討ge is alternating squ火劇are wave; for the latte海師r, the DC current is nearly const子謝ant and the output c都相urrent is alternatin秒嗎g square wave.
7. According to the waveform o黑好f inverter output voltage or cur吧妹rent, it can be divided into sine wa劇物ve output inverter and non si地低ne wave output inverter.
8. According to亮校 the inverter control mode討放, it can be divided into frequency m路多odulation (PFM) inver弟地ter and pulse width modulation (PW兵器M) inverter.
9. According to the working mode森線 of inverter switch circuit, it can b西的e divided into resonant inverter,在雪 fixed frequency hard switch invert亮門er and fixed frequency soft switch in分要verter.
10. It can be divided into 靜費load converter inverter 務師and self converter inverter 她刀according to inverter converter m關又ode.
